The IAU FITS Working Group is established under IAU Commission 5. Below are the available Triannual Reports and the transactions of the Business Meetings that are held at each IAU General Assembly meeting (every 3 years). A few other available status reports of IAU FWG activities are also listed. The annual reports of the American Astronomical Society Working Group on Astronomical Software (available here) also summarize some of the activities of the IAU FWG.

The principal forum for FITS announcements and discussion is the FITSBITS email list. View the FITSBITS email archive (general FITS-related discussions). Further general information about FITS may be obtained from the FITS Support Office web site.
